Bellows Seal Stop Valve Double Seal Flange Connection
Stop Valve Description
The bellows stop valve adopts bellows structure inside, and the lower end of the stainless steel bellows is welded on the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the bonnet to form a static seal. The double seal design is adopted to avoid leakage if the bellows fails and the stem packing is welded to the valve stem to maintain stable operation performance and avoid the vibration of the valve stem caused by the vibration of the valve plug. It is most suitable for pipelines of steam, flammable, explosive, heat transfer oil, high-purity, toxic and other media.
